java.lang.Object | +--org.bouncycastle.graphics.rt.objects.DirectionalLight
a directional light - the basic spotlight. This defines a light with as a point source with the light being shined on objects that fall within the cone described by the lights outside angle and direction.
By default is affects all objects unless the addAffected method is used, in which case it only affects those objects specified.
Example:
<DirectionalLight location="0, 0, 0" direction="0, 0, -1" color="0.8, 0.7, 1"/>
